Introduction
Laravel's events provide a simple observer pattern implementation, allowing you to subscribe and listen for various events that occur within your application. Event classes are typically stored in the app/Events
directory, while their listeners are stored in app/Listeners
. Don't worry if you don't see these directories in your application as they will be created for you as you generate events and listeners using Artisan console commands.
Events serve as a great way to decouple various aspects of your application, since a single event can have multiple listeners that do not depend on each other. For example, you may wish to send a Slack notification to your user each time an order has shipped. Instead of coupling your order processing code to your Slack notification code, you can raise an App\Events\OrderShipped
event which a listener can receive and use to dispatch a Slack notification.
Registering Events & Listeners
The App\Providers\EventServiceProvider
included with your Laravel application provides a convenient place to register all of your application's event listeners. The listen
property contains an array of all events (keys) and their listeners (values). You may add as many events to this array as your application requires. For example, let's add an OrderShipped
event:
use App\Events\OrderShipped;
use App\Listeners\SendShipmentNotification;
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
OrderShipped::class => [
SendShipmentNotification::class,
],
];
{tip} The
event:list
command may be used to display a list of all events and listeners registered by your application.
Generating Events & Listeners
Of course, manually creating the files for each event and listener is cumbersome. Instead, add listeners and events to your EventServiceProvider
and use the event:generate
Artisan command. This command will generate any events or listeners that are listed in your EventServiceProvider
that do not already exist:
php artisan event:generate
Alternatively, you may use the make:event
and make:listener
Artisan commands to generate individual events and listeners:
php artisan make:event PodcastProcessed
php artisan make:listener SendPodcastNotification --event=PodcastProcessed
Manually Registering Events
Typically, events should be registered via the EventServiceProvider
$listen
array; however, you may also register class or closure based event listeners manually in the boot
method of your EventServiceProvider
:
use App\Events\PodcastProcessed;
use App\Listeners\SendPodcastNotification;
use Illuminate\Support\Facades\Event;
/**
* Register any other events for your application.
*
* @return void
*/
public function boot()
{
Event::listen(
PodcastProcessed::class,
[SendPodcastNotification::class, 'handle']
);
Event::listen(function (PodcastProcessed $event) {
//
});
}
Queueable Anonymous Event Listeners
When registering closure based event listeners manually, you may wrap the listener closure within the Illuminate\Events\queueable
function to instruct Laravel to execute the listener using the queue:
use App\Events\PodcastProcessed;
use function Illuminate\Events\queueable;
use Illuminate\Support\Facades\Event;
/**
* Register any other events for your application.
*
* @return void
*/
public function boot()
{
Event::listen(queueable(function (PodcastProcessed $event) {
//
}));
}
Like queued jobs, you may use the onConnection
, onQueue
, and delay
methods to customize the execution of the queued listener:
Event::listen(queueable(function (PodcastProcessed $event) {
//
})->onConnection('redis')->onQueue('podcasts')->delay(now()->addSeconds(10)));
If you would like to handle anonymous queued listener failures, you may provide a closure to the catch
method while defining the queueable
listener. This closure will receive the event instance and the Throwable
instance that caused the listener's failure:
use App\Events\PodcastProcessed;
use function Illuminate\Events\queueable;
use Illuminate\Support\Facades\Event;
use Throwable;
Event::listen(queueable(function (PodcastProcessed $event) {
//
})->catch(function (PodcastProcessed $event, Throwable $e) {
// The queued listener failed...
}));
Wildcard Event Listeners
You may even register listeners using the *
as a wildcard parameter, allowing you to catch multiple events on the same listener. Wildcard listeners receive the event name as their first argument and the entire event data array as their second argument:
Event::listen('event.*', function ($eventName, array $data) {
//
});
Event Discovery
Instead of registering events and listeners manually in the $listen
array of the EventServiceProvider
, you can enable automatic event discovery. When event discovery is enabled, Laravel will automatically find and register your events and listeners by scanning your application's Listeners
directory. In addition, any explicitly defined events listed in the EventServiceProvider
will still be registered.
Laravel finds event listeners by scanning the listener classes using PHP's reflection services. When Laravel finds any listener class method that begins with handle
, Laravel will register those methods as event listeners for the event that is type-hinted in the method's signature:
use App\Events\PodcastProcessed;
class SendPodcastNotification
{
/**
* Handle the given event.
*
* @param \App\Events\PodcastProcessed $event
* @return void
*/
public function handle(PodcastProcessed $event)
{
//
}
}
Event discovery is disabled by default, but you can enable it by overriding the shouldDiscoverEvents
method of your application's EventServiceProvider
:
/**
* Determine if events and listeners should be automatically discovered.
*
* @return bool
*/
public function shouldDiscoverEvents()
{
return true;
}
By default, all listeners within your application's app/Listeners
directory will be scanned. If you would like to define additional directories to scan, you may override the discoverEventsWithin
method in your EventServiceProvider
:
/**
* Get the listener directories that should be used to discover events.
*
* @return array
*/
protected function discoverEventsWithin()
{
return [
$this->app->path('Listeners'),
];
}
Event Discovery In Production
In production, it is not efficient for the framework to scan all of your listeners on every request. Therefore, during your deployment process, you should run the event:cache
Artisan command to cache a manifest of all of your application's events and listeners. This manifest will be used by the framework to speed up the event registration process. The event:clear
command may be used to destroy the cache.
Defining Events
An event class is essentially a data container which holds the information related to the event. For example, let's assume an App\Events\OrderShipped
event receives an Eloquent ORM object:
<?php
namespace App\Events;
use App\Models\Order;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class OrderShipped
{
use Dispatchable, InteractsWithSockets, SerializesModels;
/**
* The order instance.
*
* @var \App\Models\Order
*/
public $order;
/**
* Create a new event instance.
*
* @param \App\Models\Order $order
* @return void
*/
public function __construct(Order $order)
{
$this->order = $order;
}
}
As you can see, this event class contains no logic. It is a container for the App\Models\Order
instance that was purchased. The SerializesModels
trait used by the event will gracefully serialize any Eloquent models if the event object is serialized using PHP's serialize
function, such as when utilizing queued listeners.
Defining Listeners
Next, let's take a look at the listener for our example event. Event listeners receive event instances in their handle
method. The event:generate
and make:listener
Artisan commands will automatically import the proper event class and type-hint the event on the handle
method. Within the handle
method, you may perform any actions necessary to respond to the event:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
class SendShipmentNotification
{
/**
* Create the event listener.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Handle the event.
*
* @param \App\Events\OrderShipped $event
* @return void
*/
public function handle(OrderShipped $event)
{
// Access the order using $event->order...
}
}
{tip} Your event listeners may also type-hint any dependencies they need on their constructors. All event listeners are resolved via the Laravel service container, so dependencies will be injected automatically.
Stopping The Propagation Of An Event
Sometimes, you may wish to stop the propagation of an event to other listeners. You may do so by returning false
from your listener's handle
method.
Queued Event Listeners
Queueing listeners can be beneficial if your listener is going to perform a slow task such as sending an email or making an HTTP request. Before using queued listeners, make sure to configure your queue and start a queue worker on your server or local development environment.
To specify that a listener should be queued, add the ShouldQueue
interface to the listener class. Listeners generated by the event:generate
and make:listener
Artisan commands already have this interface imported into the current namespace so you can use it immediately:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendShipmentNotification implements ShouldQueue
{
//
}
That's it! Now, when an event handled by this listener is dispatched, the listener will automatically be queued by the event dispatcher using Laravel's queue system. If no exceptions are thrown when the listener is executed by the queue, the queued job will automatically be deleted after it has finished processing.
Customizing The Queue Connection & Queue Name
If you would like to customize the queue connection, queue name, or queue delay time of an event listener, you may define the $connection
, $queue
, or $delay
properties on your listener class:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendShipmentNotification implements ShouldQueue
{
/**
* The name of the connection the job should be sent to.
*
* @var string|null
*/
public $connection = 'sqs';
/**
* The name of the queue the job should be sent to.
*
* @var string|null
*/
public $queue = 'listeners';
/**
* The time (seconds) before the job should be processed.
*
* @var int
*/
public $delay = 60;
}
If you would like to define the listener's queue at runtime, you may define a viaQueue
method on the listener:
/**
* Get the name of the listener's queue.
*
* @return string
*/
public function viaQueue()
{
return 'listeners';
}
Conditionally Queueing Listeners
Sometimes, you may need to determine whether a listener should be queued based on some data that are only available at runtime. To accomplish this, a shouldQueue
method may be added to a listener to determine whether the listener should be queued. If the shouldQueue
method returns false
, the listener will not be executed:
<?php
namespace App\Listeners;
use App\Events\OrderCreated;
use Illuminate\Contracts\Queue\ShouldQueue;
class RewardGiftCard implements ShouldQueue
{
/**
* Reward a gift card to the customer.
*
* @param \App\Events\OrderCreated $event
* @return void
*/
public function handle(OrderCreated $event)
{
//
}
/**
* Determine whether the listener should be queued.
*
* @param \App\Events\OrderCreated $event
* @return bool
*/
public function shouldQueue(OrderCreated $event)
{
return $event->order->subtotal >= 5000;
}
}
Manually Interacting With The Queue
If you need to manually access the listener's underlying queue job's delete
and release
methods, you may do so using the Illuminate\Queue\InteractsWithQueue
trait. This trait is imported by default on generated listeners and provides access to these methods:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
class SendShipmentNotification implements ShouldQueue
{
use InteractsWithQueue;
/**
* Handle the event.
*
* @param \App\Events\OrderShipped $event
* @return void
*/
public function handle(OrderShipped $event)
{
if (true) {
$this->release(30);
}
}
}
Queued Event Listeners & Database Transactions
When queued listeners are dispatched within database transactions, they may be processed by the queue before the database transaction has committed. When this happens, any updates you have made to models or database records during the database transaction may not yet be reflected in the database. In addition, any models or database records created within the transaction may not exist in the database. If your listener depends on these models, unexpected errors can occur when the job that dispatches the queued listener is processed.
If your queue connection's after_commit
configuration option is set to false
, you may still indicate that a particular queued listener should be dispatched after all open database transactions have been committed by defining an $afterCommit
property on the listener class:
<?php
namespace App\Listeners;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
class SendShipmentNotification implements ShouldQueue
{
use InteractsWithQueue;
public $afterCommit = true;
}
{tip} To learn more about working around these issues, please review the documentation regarding queued jobs and database transactions.
Handling Failed Jobs
Sometimes your queued event listeners may fail. If queued listener exceeds the maximum number of attempts as defined by your queue worker, the failed
method will be called on your listener. The failed
method receives the event instance and the Throwable
that caused the failure:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
class SendShipmentNotification implements ShouldQueue
{
use InteractsWithQueue;
/**
* Handle the event.
*
* @param \App\Events\OrderShipped $event
* @return void
*/
public function handle(OrderShipped $event)
{
//
}
/**
* Handle a job failure.
*
* @param \App\Events\OrderShipped $event
* @param \Throwable $exception
* @return void
*/
public function failed(OrderShipped $event, $exception)
{
//
}
}
Specifying Queued Listener Maximum Attempts
If one of your queued listeners is encountering an error, you likely do not want it to keep retrying indefinitely. Therefore, Laravel provides various ways to specify how many times or for how long a listener may be attempted.
You may define $tries
property on your listener class to specify how many times the listener may be attempted before it is considered to have failed:
<?php
namespace App\Listeners;
use App\Events\OrderShipped;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
class SendShipmentNotification implements ShouldQueue
{
use InteractsWithQueue;
/**
* The number of times the queued listener may be attempted.
*
* @var int
*/
public $tries = 5;
}
As an alternative to defining how many times a listener may be attempted before it fails, you may define a time at which the listener should no longer be attempted. This allows a listener to be attempted any number of times within a given time frame. To define the time at which a listener should no longer be attempted, add a retryUntil
method to your listener class. This method should return a DateTime
instance:
/**
* Determine the time at which the listener should timeout.
*
* @return \DateTime
*/
public function retryUntil()
{
return now()->addMinutes(5);
}
Dispatching Events
To dispatch an event, you may call the static dispatch
method on the event. This method is made available on the event by the Illuminate\Foundation\Events\Dispatchable
trait. Any arguments passed to the dispatch
method will be passed to the event's constructor:
<?php
namespace App\Http\Controllers;
use App\Events\OrderShipped;
use App\Http\Controllers\Controller;
use App\Models\Order;
use Illuminate\Http\Request;
class OrderShipmentController extends Controller
{
/**
* Ship the given order.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$order = Order::findOrFail($request->order_id);
// Order shipment logic...
OrderShipped::dispatch($order);
}
}
{tip} When testing, it can be helpful to assert that certain events were dispatched without actually triggering their listeners. Laravel's built-in testing helpers makes it a cinch.
Event Subscribers
Writing Event Subscribers
Event subscribers are classes that may subscribe to multiple events from within the subscriber class itself, allowing you to define several event handlers within a single class. Subscribers should define a subscribe
method, which will be passed an event dispatcher instance. You may call the listen
method on the given dispatcher to register event listeners:
<?php
namespace App\Listeners;
class UserEventSubscriber
{
/**
* Handle user login events.
*/
public function handleUserLogin($event) {}
/**
* Handle user logout events.
*/
public function handleUserLogout($event) {}
/**
* Register the listeners for the subscriber.
*
* @param \Illuminate\Events\Dispatcher $events
* @return void
*/
public function subscribe($events)
{
$events->listen(
'Illuminate\Auth\Events\Login',
[UserEventSubscriber::class, 'handleUserLogin']
);
$events->listen(
'Illuminate\Auth\Events\Logout',
[UserEventSubscriber::class, 'handleUserLogout']
);
}
}
Registering Event Subscribers
After writing the subscriber, you are ready to register it with the event dispatcher. You may register subscribers using the $subscribe
property on the EventServiceProvider
. For example, let's add the UserEventSubscriber
to the list:
<?php
namespace App\Providers;
use App\Listeners\UserEventSubscriber;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
//
];
/**
* The subscriber classes to register.
*
* @var array
*/
protected $subscribe = [
UserEventSubscriber::class,
];
}

Ch.2 P1: True or False?
a. A user requests a Web page that consists of some text and three images. For this page, the client will send one request message and receive four response messages.
b. Two distinct webpages can be sent over the same persistent connection.
c. With nonpersistent connections between browser and origin server, it is possible for a singe TCP segment to carry two distinct HTTP request messages.
d. The Date: header in the HTTP response message indicates when the object in the response was last modified.
e. HTTP response messages never have an empty message body.
a. True
b. True
c. False
d. False
e. True
Ch.3 P3: UDP and TCP use 1s complement for their checksums. Suppose you have the following three 8-bit bytes: 01010011, 01100110, 01110100. What is the 1s complement of the sum of these 8-bit bytes? (Note that although UDP and TCP use 16-bit words in computing the checksum, for this problem you are being asked to consider 8-bit sums.) Show all work. Why is it that UDP takes the 1s complement of the sum; that is, why not just use the sum? With the 1s complement scheme, how does the receiver detect errors? Is it possible that a 1-bit error will go undetected? How about a 2-bit error?
1 11
01010011
+ 01100110
= 10111001
111 11
10111001
+ 01110100
= 00101110
1's compliment: 11010001
UDP takes the 1's compliment because when it is added to the sum, it should read 11111111.
If there is a zero, then there is an error.
It isn't possible for a 1 bit error to make it through, but a 2 bit error could if the 2 bits canceled each other out.
For example: if the last bit of the first byte was changed to a zero and the last bit of the second byte was changed to a 1, the result of the checksum would be the same.

Trends
As the title suggests, this article is on trends and the associated effects of following them. Trends also known as fads can be defined as forms of behavior which becomes popular in a collective group of people and is followed enthusiastically by them. Trends mostly develop as the product of peer pressure and also because such behavior is espoused to be cool by the social or other media.
Such behavior by people is explained by an effect called “Bandwagon Effect” which states that more the people following a particular fad, more will be the number who will join in that particular fad. The year 2014 saw the emergence of the “Ice Bucket Challenge” which challenged people to dump a bucket of ice-cold water on themselves and then nominate others to follow suit. This act designed to raise awareness about the ALS or Lou Gehrig’s Disease saw a lot of takers in several countries across the world. India also saw numerous celebrities taking up the challenge. This led to the practice being followed by members of the general public who just blindly aped the trend without any gain to their knowledge about the disease.
Hashtags And The Hogwash
This is not the only example of situations in which people were intent only on blindly aping the celebrities and this certainly leads us to think about the general degeneration of the public mindset. We are content to think that following a few social trends on the social media makes us valuable citizens of the society and also takes care of all our social responsibilities. This is certainly a deplorable situation.
Perhaps, one of the most irritating trends of today is the excessive use of hashtags. Hash character is quite a common computational symbol. But, when combined to a word or phrase it acts as a label by which specific topics can be accessed. This certainly is a useful characteristic and is hence used by microblogging sites like Twitter and picture sharing sites like Instagram. Unfortunately, we have indulged in misusing such a powerful tool by creating useless content. We have often come across posts on social media platforms which tend to have an astounding number of hashtags in them. These hashatgs which have no apparent use certainly serve to exacerbate the pain of reading through the post. Hashtags like #lonely, #mafia ,#chilling_out when combined to an innumerable number of tags does not make one seem cool.
Concluding Note
This article might seem like a diatribe against the popular culture of our times. It is not certainly meant to be such a piece. Rather, it is just an attempt to dissuade people from indulging in blatant imitation of fads as they serve no purpose to anyone. We should be aware of the reason behind a particular fad as blindly aping them is like a mockery of the social causes which induce them. Trends in fashion are certainly not related to these and following them depends on the personal likes or dislikes. But, awareness is certainly essential for trends which require our conscious efforts.

How long has Justin Timberlake been married to Jessica Biel?
Justin Timberlake has hit the headlines after he was spotted holding hands with the co-star of his forthcoming movie Palmer earlier this week.
The 38-year-old pop star and actor was spotted with Alisha Wainwright, who appears with him in the football drama – sparking speculation although a source told Mail Online there is ‘nothing going on’ between the two of them.
Justin is of course married to actress Jessica Biel, – who fell for the former NSYNC singer despite admitting she wasn’t a fan of the boyband.
But how long have they been together – and who has Justin dated in the past?
Here’s what you need to know…
How long have Justin Timberlake and Jessica Biel been married?
The two superstars started dating in January 2007.
The two had a temporary break in March 2011, releasing a statement to People magazine insisting they’ll ‘remain friends and continue to hold the highest level of love and respect for each other.’
Advertisement Advertisement
You can’t clip the wings of two true love birds, though and they reconciled around June.
They became engaged in December 2011 and married on October 19 2012 at the Borgo Egnazia resort in Fasano, Italy.
In 2015, the two welcomed their son Silas Randall.
And perhaps their most important milestone – in 2019, Jessica Biel won Halloween, dressing as her hubby in his NSYNC get-up.
Justin Timberlake’s dating history
Britney Spears
How could anyone forget Britney and Justin?
Meeting as youngsters in Disney’s Mickey Mouse Club, the two grew up together and dated from 1998 to 2002.
During their tenure as America’s Sweethearts, they gave us such iconic moments as the matching denim outfit – which is still recreated by the likes of Kendall Jenner, Katy Perry, and Jake Paul and Tana Mongeau.
When they first broke up, cheating rumours were banded around – with Timberlake’s own Cry Me a River adding fuel to the fire.
However, the two have remained pretty amicable over the years.
In a 2011 Vanity Fair interview, Justin said: ‘I wish her the best—that goes without saying. We haven’t spoken in nine or 10 years.’
Cameron Diaz
Justin dated Hollywood star Cameron Diaz for four years, from 2003 to 2007.
The two never revealed what led to their break-up, but they stayed on good terms.
So much so that they’ve worked together twice since breaking up – in 2007’s Shrek the Third and in 2011’s Bad Teacher.
Fergie
Advertisement Advertisement
Stacey ‘Fergie’ Ferguson of Black Eyed Peas fame dated Justin in 1997.
She told Bravo’s Andy Cohen that theirs wasn’t ‘all that serious’ a thing.
The singer ended up as the opening act for Justin’s 2007 FutureSex/LoveShow tour.
Alyssa Milano
Charmed actress Alyssa and Justin briefly dated in 2002.
This was the same year he broke up with Britney – and broke hearts the world over.
Even Alyssa thought Justin and Britney were ‘the perfect match’ as she told Entertainment Tonight in 2015.

Whut you say, dah? huh, uh! chile,

Di’n’ I tell you th’ee las’ night?
Go ‘way, honey, you ain’t right.
I got somep’n’ else to do,
‘Cides jes’ tellin’ tales to you.
Tell you jes’ one? Lem me see
Whut dat one’s a–gwine to be.
When you ’s ole, yo membry fails;
Seems lak I do’ know no tales.
Well, set down dah in dat cheer,
Keep still ef you wants to hyeah.
Tek dat chin up off yo’ han’s,
Set up nice now. Goodness lan’s!
Hol’ yo’se’f up lak yo’ pa.
Bet nobidy evah saw
Him scrunched down lak you was den—
High–tone boys meks high–tone men.
Once dey was a ole black bah,
Used to live ‘roun’ hyeah some whah
In a cave.
An’ he had two gread big eyes,
Jes’ erbout a saucer’s size.

But you ought to seen his paws!
Did I see ‘em? How you ‘spec
I ’s a–gwine to ricollec’
Dis hyeah ya’n I ’s try’n’ to spin
Ef you keeps on puttin’ in?

Dis hyeah bah ‘d go trompin’ ‘roun’
Eatin’ evahthing he foun’;
No one could n’t have a fa’m
But dat bah ‘u’d do’ em ha’m;
And dey could n’t ketch de scamp.
Anywhah he wan’ed to tramp.
Dah de scoun’el ‘d mek his track,
Do his du’t an’ come on back.
He was sich a sly ole limb,
Traps was jes’ lak fun to him.
Now, down neah whah Mistah Bah
Lived, dey was a weasel dah;
But dey was n’t fren’s a–tall
Case de weasel was so small.
An’ de bah ‘u’d, jes’ fu’ sass,
Tu’n his nose up w’en he ‘d pass.
Weasels ’s small o’ cose, but my!
Dem air animiles is sly.
So dis hyeah one says, says he,
“I ‘ll jes’ fix dat bah, you see.”
So he fixes up his plan
An’ hunts up de fa’merman.
When de fa’mer see him come,
He ‘mence lookin’ mighty glum,
An’ he ketches up a stick;
But de weasel speak up quick:
“Hol’ on, Mistah Fa’mer man,
I wan’ ‘splain a little plan.
Ef you waits, I ‘ll tell you whah
An’ jes’ how to ketch ol’ Bah.

Den de man he scratch his haid,
Las’ he say, “I’ll mek de trade.”
So de weasel et his hen,
Smacked his mouf and says, “Well, den,
Set yo’ trap an’ bait ternight,
An’ I ‘ll ketch de bah all right.”
Den he ups an’ goes to see
Mistah Bah, an’ says, says he:
“Well, fren’ Bah, we ain’t been fren’s,
But ternight ha’d feelin’ ‘en’s.

Cose I would n’t come to you,
But it mus’ be done by two;
Hit’s a trap, but we kin beat
All dey tricks an’ git de meat.”
“Cose I ’s wif you,” says de bah,
“Come on, weasel, show me whah.”
Well, dey trots erlong ontwell
Dat air meat beginned to smell
In de trap. Den weasel say:
“Now you put yo’ paw dis way
While I hol’ de spring back so,
Den you grab de meat an’ go.”
Well, de bah he had to grin
Ez he put his big paw in,
Den he juked up, but—kerbing!
Weasel done let go de spring.
“Dah now,” says de weasel, “dah,
I done cotched you, Mistah Bah!”
O, dat bah did sno’t and spout,
Try’n’ his bestes’ to git out,
But de weasel say, “Goo’–bye!
Weasel small, but weasel sly.”
Den he tu’ned his back an’ run
Tol’ de fa’mer whut he done.
So de fa’mer come down dah,
Wif a axe and killed de bah.
Dah now, ain’t dat sto’y fine?
Run erlong now, nevah min’.
Want some mo’, you rascal, you?
No, suh! no, suh! dat ‘ll do.


i decided that for my first ayahusca expericence i should try it in the outdoors. i ended up going to the bike trails i used to take when i was a kid. the trails go for miles, and the chances of being bothered at night were slim. so i arrive at the trails about 11pm, and about that time i drank about 50 grams worth of caapi.
about fifteen minuets later I'm starting to be able to tell that the caapi is going to work, so i bust out my little zen player, and as I'm messing with it i stepped onto something with a little cushion. well it didn't automatically register, and i kept on moving about 5 feet till i looked back and saw that i stepped onto a medium sized snake. right about there i started having second thoughts about my adventure. no matter the snakes and a few pesky spider webs littering the trail, the music calmed me enough to head on down the trail.
about thirty minuets into the caapi i took the dmt pill. well about 45 minuets later i'm hacking my way down the trail and having a pretty good body high, not really having an visuals until a dead mesquito dead center the trail is hanging from a thread of spider silk. this stopped me in my tracks and was in sync with stinkfist coming onto my zen player. as i stared at it i saw in the background a faint spider web ballooning outwards and as i tried to focus my light on it i realized that it was a hallucination.
i sat there and watched the mosquito dance in the wind, in time to the music i was hearing. very assume. well i moved on deeper into the woods, and about thirty minuites later the trip starts really getting involved, in a good way. feelings i haven't felt since the last time i tripped on mushrooms suddenly came to me in a powerfull way. i came to a clearing on the woodline and i stopped there to admire its beauty, the leaves made like an arch to let the traveler see the moon gently cradled in clouds over the tall grass moving in the wind.
at about 1:00am i'm tripping pretty good, good enough to loose my way on the trail. i start having a slight panic attack cause i knew the worst was to come and i didn't want to do it in the middle of the woods, with snakes and spiders and no clue where I'm at. so it takes me about thirty minutes to finally stumble unto the right path back to my car, and about another 25 minuets to reach it. by the time i get back I'm tripping very good, nature is truly beautiful at night, no way to describe it. i leave my backpack at the car and i head down to the picnic table underneath a huge maple tree. i layed down on top of the table and listened to a very tribal song by white zombie.
towards the end of the song i can feel the trip starting to take a turn, at first it felt good, but a few minuets pass and i instantly realize I'm going on the carnival ride to the truth i last visited on mushrooms, to the pain of dying in the viod, of buring disreality. i layed there squirming on the picnic table, because it felt like i was dying in the cold. it started to feel like i was being sucked down by a swirl and at the same time being tumbled in a dryer. i don't really know how to put exactly what thought was causing my distress but i know it had to do with dying in a cold void alone, and somehow this was gods pain.
i definantly wasen't enjoying the trip anymore, i had lost my basic motor capabilities and wasn't able to focus my eyes on anything at all. somehow, after some torment, i got up and stumbled down the sidewalk to try to get to my car. at this point I'm really glad that nobody else was around cause they would've definantly called the police. i couldn't walk a straight line, and started tumbling down into the tree line. that was horrifying, cause i couldn't get out. i fought the ayahusca cause i started to feel it take me out of my world and into its. it was kinda like the simpsons when they went 3d. well, it also felt like the matrix, really sythenic kind of trip.
so i'm unable to get back on my feet, and i'm rolling around in this thorn patch. every time i fell on my back i'd keep falling long after my body hit the ground, and at the same time being tormented by gods pain over and over. images of stephen kings 'it' was revolving in my head. mutiple forces were driving me: i died in the lonley sewer in some clowns evil game, i died underneath a bridge, i died on the side of the road, and came back to life as a cactus blooms in the desert(planet earth show), and the morning sky, and when keanu realizes he's the one and bursts from the core.
the cycle of falling in circles while dying and being rebirthed was accompanied by vomiting and the fact that the fucking thorns and grass were reconstituting my body. it slithered on my skin and i could taste it in my mouth, the plants were eating me, and really they were. all i could do was hyperventilate and muter omfg and yawasuca and being sorry about coming there (i was unwelcome). finally, after some time i was able to focuse my energy on operating my body to get free of that damn thorn bush and getting to my car.
i realized that i had a really difficult time operating my hands, i wasn't able to feel the objects i was handling, and the feeling of being tumbled in a dryer was more pronounced. but finally i got to my car, and checking the time was surprised to see it was 5:00am. but all went good, i made it through with just some deep scratches from the thorns all over my body and some kind of welts on my back, and a new found respect for my everyday illusion of sanity.

The specification's type, which can be a maturity level (e.g. Working Draft) if it is on a publication track but can also take other values for other types of documents (e.g. "unofficial" for, well, unofficial documents).
| value | meaning |
|---|---|
| base | Just the basic template, not a specification. Use this for public documentation produced by a group that has no current clear plan to be officially published. Example |
| MO | Member-Only Document. Similar to base, but for documents that need to be clearly flagged as being restricted in access to W3C Members. This is rarely, if ever, useful. Example |
| unofficial | An unofficial draft. Use this if you're producing a document outside of W3C but want to use styles that match those of W3C specifications, for instance to propose a new document while hosting it on your own server. Note that this automatically licences the content under CC-BY v3.0. If you want a different copyright, you will need to set the various copyright configuration options. Example |
| ED | Editor's Draft. Use this for documents that are maintained in the group's own repository. Requires edDraftURI to be specified. This is the default value. Example |
| FPWD | First Public Working Draft. Example |
| WD | Working Draft. Requires previousPublishDate and previousMaturity. Example |
| LC | Last Call Working Draft. Requires previousPublishDate, previousMaturity, and lcEnd. Example |
| CR | Candidate Recommendation. Requires previousPublishDate, previousMaturity, and crEnd. Example |
| PR | Proposed Recommendation. Requires previousPublishDate and previousMaturity. Example |
| PER | Proposed Edited Recommendation. Requires previousPublishDate and previousMaturity. Example |
| REC | Recommendation. Requires previousPublishDate and previousMaturity. Example |
| RSCND | Rescinded Recommendation. Requires previousPublishDate and previousMaturity. I wish there were more of those. The style is so edgy. Example |
| NOTE | Deprecated. A note. It is unclear to me how this differs from the more specific WG-NOTE and friends. Do not use this. Example |
| FPWD-NOTE | First Public Working Draft of a Note (of any kind, it would seem). Example |
| WG-NOTE | Working Group Note. Example |
| BG-DRAFT, BG-FINAL | Business Group Draft or Final Report. Example Draft Report |
| CG-DRAFT, CG-FINAL | Community Group Draft or Final Report. Example Draft Report |
| IG-NOTE |
Interest Group Note. For this, charterDisclosureURI is required.
Example |
| Member-SUBM | Member Submission. Note that ReSpec uses the default W3C copyright for this, but that you are entitled to retain your own copyright instead of transferring it to W3C. Use the copyright options for this. Example |
| Team-SUBM | Team Submission. Example |
| XGR | Deprecated. Incubator Group Report. Requires xgrGroupShortName and xgrDocShortName. Example |
| draft-finding | Draft TAG Finding. If you are one of the Nine and working on a Finding, this is for you. Note that for findings, ReSpec currently does not support very robust SotD generation (there don't seem to be solid rules for what constitutes a valid Finding SotD) so you'll have to specify your own. If there are rules that could be used, please report a bug. ReSpec further assumes some conventions for finding URLs that are not consistent throughout all of the TAG's repository, specifically that all findings live in "http://www.w3.org/2001/tag/doc/", that the latest version is at "http://www.w3.org/2001/tag/doc/shortName", and that the dated versions are at "shortName-YYYYMMDD". Example |
| finding | TAG Finding. Same as above, but final. Example |

Bee Simulator has moments of fun, but is otherwise a letdown
Some subjects are just better suited for simulators than others.
by Jennifer LockeSource: Bigben Interactive
First, there was Goat Simulator. And Farming Simulator. And Euro Truck Simulator. And Flight Simulator. Well, now there's Bee Simulator. You can guess what the game's all about. You play as a buzzing little bumblebee, collecting pollen for your hive to prepare for the winter. It's fun in fleeting moments, but not the type of simulator I can see people sticking with.
At a glance
Bee Simulator
Bottom line: Bee Simulator is fun for a short time, but won't keep people's attention for long. Its charm can't save it from boredom. When you throw in the price tag, it's tough to recommend.
The Good
- Oddly charming
- Collecting pollen can be relaxing for a short time
- Different mini-games
- Educational
The Bad
- Price is expensive
- Can get boring quickly
- The voice acting is rough
- The visuals are dated
Bee Simulator What I like
Source: Bigben Interactive
I remember as a kid playing LeapFrog learning games and reading all sorts of books about insects and bugs. Bee Simulator acts as an intersection between those. There are neat little facts about bees throughout its loading screens, and there are sections where you can read up on other insect facts as well. It's educational, and I like that. That may not be its primary purpose because of the way the game is designed, but these facts are welcome additions regardless. I learned some interesting things I may never have known otherwise. Did you know a honey bee's wings can flap at 200 beats per second, creating its distinctive buzzing sound? Now you do.
There's a charm to Bee Simulator that you can't help but like.
There's also a charm to Bee Simulator that you can't help but like. The idea is cute. Buzzing around and collecting pollen can be relaxing and a nice change of pace from your typical shooters or expansive RPGs. I had fun flying around — even though the controls took me a bit to get used to — trying to find the rarest pollen I could. The problem is that this is enjoyment is fleeting.
Its mini-games thankfully allow you to do things other than collect pollen. Challenge a wasp to turn-based fight, race against another friendly bee. Or just go around and sting people. Whatever works for you.
Bee Simulator What I don't like
Source: Bigben Interactive
I can't see people spending more than a couple of hours in Bee Simulator. You can argue that it's not meant for players to be in it for the long haul, but it still can't grab your attention as long as it should. Maybe it's also the time of year it released. I found myself gravitating towards other games. The gameplay loop just isn't addicting nor fun after a while.
I don't think it's worth $40.
I don't know what Bee Simulator cost to make. A $40 price tag might be totally justifiable from the developer's standpoint. They need to make money, and games aren't cheap to develop. But for consumers playing the game, I don't think it's worth $40. People already hate spending $60 on AAA experiences and, even though I think they should cost more, it's a difficult sell when you can buy games for much less.
And despite how beautiful some of the screenshots make it look, the visuals aren't all that appealing. They're dated. Some games can get away with rougher visuals, especially if they lean towards a stylized nature, but this isn't one of them. All I could think about was how ugly, and lifeless the park looked.
To cap it off, the voice acting also sounds like they didn't hire real voice actors, and instead used anyone with little or no voice acting experience. Basically, what I'm saying it sounds like I could have auditioned for a part and got the role. I by no means think my voice acting capabilities would be good. Again, not every game needs top-of-the-line professional voice actors. I'm not expecting Troy Baker or Laura Bailey to jump on Bee Simulator. But if the acting you can get sounds as amateurish as it does, just don't put any voice acting in all together. Most of the humans only communicate in grunts anyway, with only some of the animals taking a bulk of the dialogue.
Should you buy Bee Simulator? Not at full price.
Source: Bigben Interactive
The charm that Bee Simulator sells in its trailers is there for a short while before turning into dull, mostly monotonous gameplay. At its core, the game isn't broken, but the foundation is so bare that you won't stick with it for long. What I found to be the most rewarding aspect was learning little tidbits about bees that I otherwise would never have known. And these usually came in the form of loading screens.
2.5 out of 5
Considering the quality of the graphics, voice acting, and expensive price, I find it hard to recommend it to anyone. Children might appreciate it more, but even then, you should wait until you can find the game on sale.

Ruby provides programmers with a range of variable types, all defined by their scope -- where they can be accessed. The variables, in order of increasing scope, are local variables, instance variables, class variables, constants, and global variables. Let's dive in to see the accessibility of each of the variable types.
First, let's start with local variables. As their name suggests, local variables have a local scope, limited to the method or block in which they are defined. They must start with a lower-case letter or underscore. Consider the following example:
def local_method
local_variable = "I'm a local variable"
5.times do
puts local_variable
end
end
local_method #=>
"I'm a local variable"
"I'm a local variable"
"I'm a local variable"
"I'm a local variable"
local_variable => # NameError: undefined local variable or method `local_variable'
In this example, the variable local_variable
is defined within the method. It can be accessed by the method itself, as we see it successfully executes the code block with the variable; but if we try to access it from outside the method, we get an error message that the variable is undefined. It's undefined because, as a local variable, its scope is limited to within the method itself. What if we were to define a local variable within block within a method?
def local_method
array = [1, 2, 3, 4, 5]
array.each do |num|
very_local_variable = "I'm a VERY local variable"
puts "#{num}. #{very_local_variable}"
end
very_local_variable
end
local_method #=>
1. I'm a VERY local variable
2. I'm a VERY local variable
3. I'm a VERY local variable
4. I'm a VERY local variable
5. I'm a VERY local variable
NameError: undefined local variable or method `very_local_variable'
What just happened? In this example, very_local_variable
is defined within a block that is within a method. When called, the method executed the block successfully, but then when very_local_variable
was called outside of the block in which it was defined, ruby told us it was undefined!  Now let's move on to instance variables.
Instance variables are variables limited to one particular instance of a class. They must begin with a single "@" character. To illustrate the scope of instance variables, consider the following example.
class Person
attr_reader :first_name, :hair_color
def initialize(first_name, hair_color)
@first_name = first_name
@hair_color = hair_color
end
end
tom = Person.new("Tom", "brown")
tom.first_name #=> "Tom"
tom.hair_color #=> "brown"
muhammad = Person.new("Muhammad", "black")
muhammad.first_name #=> "Muhammad"
muhammad.hair_color #=> "black"
When we instantiate an instance of the Person class, we must give that instance a name and hair color. In the initialize method, these two parameters are turned into instance variables which can then be accessed by other methods in the class, but only on that single instance. For example, if we call tom.first_name
, you can see that the program returns the input first name; same with the hair color. If we call these two methods on muhammad
we see that we get different results. That is precisely because @first_name
and @hair_color
c are instance variables, only to be used on a single instance of the class. In this case, tom
and muhammad
are two separate instances of the class Person
. But Tom and Muhammad are both people, after all! What if we want them to share some characteristics? For that, we'll need class variables.
Class variables are those available to every instance of that class. What is one trait that all people have in common? Consider a similar example:
class Person
attr_reader :first_name, :hair_color
def initialize(first_name, hair_color)
@first_name = first_name
@hair_color = hair_color
@@species = "homo sapiens"
end
def species
@@species
end
end
tom = Person.new("Tom", "brown")
tom.first_name #=> "Tom"
tom.hair_color #=> "brown"
tom.species #=> "homo sapiens"
muhammad = Person.new("Muhammad", "black")
muhammad.first_name #=> "Muhammad"
muhammad.hair_color #=> "black"
muhammad.species #=> "homo sapiens"
As you can see, the @@species
variable is not only available to Tom, but also to Muhammad, and every other instance of Person
!
Now let's move on to constants and global variables. These two are similar in scope, but let's start with constants. Constants must be all-caps and, traditionally, are not to be changed. Technically, Ruby does allow the user to change them, but that runs counter to their whole point of being constant, unchanging variables. Like local variables, their scope is slightly fluid. If they are defined within a class, they are available anywhere in the context of that class. If they are defined outside a class, they have global scope, which means they are accessible from anywhere. To demonstrate these concepts, let's return again to our first example:
def local_method
local_variable = "I'm a local variable"
5.times do
puts local_variable
end
end
local_method #=>
"I'm a local variable"
"I'm a local variable"
"I'm a local variable"
"I'm a local variable"
local_variable => # NameError: undefined local variable or method `local_variable'
What if we turned local_variable
into a CONSTANT? We aren't allowed to define CONSTANTS within methods, because technically every time we run the method we'd be re-assigning the constant (even though to the same string value, it would still have a different object ID every time, which isn't allowed), so let's define it outside the method.
CONSTANT_VARIABLE = "I am a CONSTANT variable"
def local_method
5.times do
puts CONSTANT_VARIABLE
end
end
local_method #=>
"I'm a CONSTANT variable"
"I'm a CONSTANT variable"
"I'm a CONSTANT variable"
"I'm a CONSTANT variable"
"I'm a CONSTANT variable"
Look! the method has access to the constant even though it's defined outside of the method! The same goes for global variables, except they actually can be defined within methods:
def local_method
array = [1, 2, 3, 4, 5]
array.each do |num|
$global_variable = "I'm a global variable!"
puts "#{num}. #{$global_variable}"
end
$global_variable
end
local_method #=>
1. I'm a global variable!
2. I'm a global variable!
3. I'm a global variable!
4. I'm a global variable!
5. I'm a global variable!
"I'm a global variable"
$global_variable #=> "I'm a global variable!"
In this example, $global_variable
is accessible anywhere, even though it was defined within a block within a method! Global variables are very powerful!
I hope you found this little explanation useful; I'm off to learn more so I can write more next time! Thanks :)
